DOOR AND WINDOW FASTENER.

To all whom it may concern:

Be it known that I, VILLIAM H. L. vVELLs, a citizen of the UnitedStates, residing at San Francisco, in the county of San Francisco andState of California, have invented new and useful Improvements in Doorand Vindow Fasteners, of which the following is a specification. 1

This invention is an improved door and window fastener to secure a dooror Window either in closed position or in partly open position, so thata door or window may be partly opened to admit air and affordventil'ation and be secured in such partly opened position to prevent anintruder from entering therethrough, the object of the invention beingto provide an improved fastener of this kind which is cheap and simplein construction, is strong and durable, may be readily operated, and maybe readily installed.

The invention consists in the features of construction, combination, andarrangement of devices, hereinafter described and claimed.

In the accompanying drawings: Figure 1 is an elevation of a fastenerconstructed and arranged in accordance with my invention and showing thesame in use as a door fastener, the door being indicated as in closedand locked position and the keeper being shown in section. Fig. 2 is aplan of the same showing the door in partly opened position. Fig. 3 isan elevation at right angles to Fig. 1 and with the door also in partlyopened position. Figs. 4 and 5 are detail sectional views. Fig. 6 is anelevation of'my improved fastener for use as a window fastener. Fig 7 isa sectional view of the same showing the upper sash in closed andfastened position in full lines and in partially lowered position indotted lines and also showing the retaining spring in normal position infull lines and in bolt releasing position in dotted lines. Fig. 8 is adetail perspective view of one of the thumb tacks used for covering theheads of the screw which secure the casing and the members of the catchtothe sash and window frame respectively.

In the embodiment of my invention, I provide a casing 1 which may beattached to a door or window and is here shown as comprising a baseplate 2 having openings 3 for the reception of securing screws, and abarrel or tubular guide member 4 on the base Specification of Letterslatent.

plate. This barrel has a transverse slot 5 and also is provided with apair of slots 6, 7 of unequal length which converge to the slot 5, theslot 6 being shorter than the slot 7. A bolt 8 is longitudinallyslidable and is also adapted to turn in the barrel or guide member 4 andhas an operating knob 9 which is connected thereto by a stem 10, saidstem being adapted to move in either of the slots 5, 6, 7. Near itsouter end, the bolt is provided with a circumferential annular groove11, providing a reduced neck 12 and a head 13.

I also provide a keeper 14 which comprises a pair of members 15, 16.Said members are adapted to be arranged with the member 15 on the outerside of the member 16 and have registering openings 17, for thereception of the screws wherewith to secure said members to one side ofthe door frame. The members 15, 16 of the keeper are respectivelyprovided with substantially semitubular portions 18, 19, whichsemi-tubular portions are provided with matching shoulders 20, 21respectively. The bolt 8 when in locking position, to secure the doorclosed, enters the tubular socket formed by the members 18, 19, as willbe understood and the stem 10 of the bolt may be turned downwardly inthe slot 5 to hold the bolt in such locking position. When the bolt 8 iswithdrawn to the full extent, so that the stem 10 is in the outer end ofthe long slot 7, the bolt is entirely disengaged from the keeper andhence the door may be opened.

In order to secure the door in partly opened position, I provide a linkbar 22 which has an opening 23 near one end that receives thesemi-tubular portion 19 of the keeper member 16, so that said link baris pivotally mounted on said keeper, the part 18 of the keeper member 15engaging the outer side of the link bar at the pivotal end of the latterand hence retaining the link bar on the pivotal portion 19. The member16 is also provided on its outer side, with a rib 241 which isconcentric with the pivotal portion 19 and which bears against one sideof the link bar and prevents the latter from being bent. The link bar isprovided near its free outer end with an opening 25 for the reception ofthe head 13 and to engage around the neck 12 of the bolt to hold thedoor in partly open position. WVhen the bolt is in such position, thestem 10 is at the outer end of the shorter slot 6. To

strengthen the link bar, the same is provided on its outer side with apair of reinforc-Y ing flanges 26.

When my improved fastener is used on a window, a strong retaining spring27 is provided which ordinarily prevents the bolt from being fullywithdrawn from the keeper and which must be disengaged from the innerend of the bolt, before the latter can be fully withdrawn as will beunderstood.

In order to cover the heads of the screws which secure the casing 1 andthe members of the catch to the sash and window frame respectively, Iprovide thumb tacks 28, the heads 29 of which cover the heads of thescrews and the stems and entering points of which are at one end of theheads 29 and may be driven into the wood and inserted through slottedenlargements 31 of the screw openings.

Having described the invention, what is claimed is:

1. In a fastener of the class described, a casing having a guideelement, a bolt mounted for sliding movement in the guide element, meansto secure the bolt in adjusted position in combination With a keeper toreceive the bolt, and a link bar pivotally mounted on the keeper, saidlever bar and bolt having devices adapting the link bar to be attachedto and detached from the bolt, the said keeper having a cylindricalsocket portion for the reception of the bolt and the said link barhaving a pivotal opening through which said cylindrical socket portionof the keeper extends.

2. In a fastener of the class described, a casing having a guideelement, a bolt mounted for sliding movement in the guide element, meansto secure the bolt in adjusted position in combination with a keeper toreceive the bolt, and a link bar pivotally mounted on the keeper, saidlever bar and bolt having devices adapting the link bar to be attachedto and detached from the bolt, the said keeper having a cylindricalsocket portion for the reception of the bolt and the said link barhaving a pivotal opening through which said cylindrical socket por-Copies of this patent may be obtained for five cents tion of the keeperextends, said keeper com prising a pair of members detachably se- 5cured together and the said cylindrical socket member comprisingsections with which said keeper members are respectively provided.

3. In a fastener of the class described, a casing having a guideelement, a bolt mounted for sliding movement in the guide element, meansto secure the bolt in adjusted position in combination with a keeper toreceive the bolt, and a link bar pivotally mounted on the keeper, saidlever bar and bolt having devices adapting the link bar to be attachedto and detached from the bolt, the said keeper having a cylindricalsocket portion for the reception of the bolt and the said link barhaving a pivotal opening through which said cylindrical socket portionof the keeper extends, said keeper comprising a pair of membersdetaehably secured together and the said cylindrical socket membercomprising sections with which said keeper members are respectivelyprovided, said sectional socket portions being provided with coengagingshoulders.

4. In a fastener of the class described, a casing having a guideelement, a bolt mounted for sliding movement in the guide element, meansto secure the bolt in adjusted position in combination with a keeper toreceive the bolt, and a link bar pivotally mounted on the keeper, saidlever bar and bolt having devices adapting the link bar to be attachedto and detached from the bolt, the said keeper having a cylindricalsocket portion for the reception of the bolt and the said link barhaving a pivotal opening through which said cylindrical socket portionof the keeper extends, and the said keeper having a rib to bear againstthe link bar and prevent the latter from bending.

In testimony whereof I affix my signature in presence of two witnesses.
